"Native pollinators in the US provide essential pollination services to agriculture which are valued at more than $9 billion annually," said Eric Lee-Mäder, pollinator program co-director at the Xerces Society, which was involved in petitions calling for the protection of the bee species.

During pollination, insects, birds and bats transfer pollen between plants, which allows them to make seeds and reproduce.

Listing the bees allows authorities to provide recovery programs and get funding for protection.
